A mark in this chapter is the brand's recognition symbol: the symbol, the pictorial logo and its variants; lettering and tone marks within the logo belong to chapter 9. Marks and colours are usually approved on screen, at large size, under office light. Then they spend most of their lives at profile-picture size, on fabric, on metal sheet, under the sun. This chapter moves the approval to exactly those places.
Quick read: the core statement, when it comes up, and the test to take home. Full read also opens the reasoning, the limits and the sources. Each principle comes before its practices, so the numbers do not run in sequence.
A mark is defined by the shape that survives at its smallest size and on its hardest material; detail is only a reward at large size.
When it comes upDrawing or approving a new mark, refreshing an old one, and when the mark is about to go into embroidery, engraving, embossing, one-colour printing or social media profile pictures. A touchpoint here is any place a customer meets the brand.
Resolution
The overall shape must stand on its own at the worst touchpoint, when all detail is gone (the same rule applies to lettering in 9.04); detail is allowed as an extra layer at large size, provided removing it does not turn the mark into a different shape.
Full reasoning
Two goods pulling against each other
A detailed mark can tell a story, looks rich and premium at large size, and makes the owner feel the effort was worth the money. A compact mark survives at small size and on rough materials, but is easily dismissed as too simple.
Why it holds
When reduced or moved onto rough materials, a mark loses things in an almost fixed order: gradients go first, then thin strokes, then narrow gaps fill in. What remains last is the outline and a few large solid areas. An embroidery stitch has its width, a laser beam has its spread, a thermal printer has only one colour, a profile picture is cropped into a circle and compressed. If people recognise the mark by its detail, then in those places they are looking at a different shape, and recognition splits in two instead of accumulating (0.2, 0.4). Those small and rough places are often where the mark appears most: chat lists, uniforms, seals, company stamps.
When it fails
If an old mark is already recognised by a detail, that detail is an asset (1.02); keep it in the main version and draw a regulated simplified version, rather than whittling the main version to fit small sizes. A brand that lives where its mark always appears large, such as buildings or premium products in large boxes, depends less on small sizes, but difficult materials still decide.
What it costs
Losing some storytelling detail. Two or three versions of the mark by size must be managed, each with rules on where it is used, and the standards keeper must know which version goes with which size.

Test a mark in four states before approval: one colour, reversed, profile-picture size in a circular frame, and embroidered on fabric.
When it comes upThe mark approval round, before the final presentation.
A test to take home
(1) One colour: fill the whole mark with one solid colour, no gradients, no extra outlines. If it is recognised at once, it passes; if it needs its colours to be recognised, it will die on company stamps, engravings and thermal printers. (2) Reversed, swapping figure and ground: a white mark on black or on a solid colour. Do gaps fill in, do solid areas turn into holes with another meaning? (3) Profile picture: place it in a circular frame and view it at its real display size in the message list on a phone, next to other profile pictures. A mark cropped at the corners by the frame, or reduced to a blur, fails. (4) Embroidery: ask the embroiderer for the smallest stroke width and smallest gap they can do on the exact fabric to be used, and compare with the mark at real embroidery size on a shirt chest; any thinner stroke or narrower gap will be merged or dropped. Best of all, embroider a sample. Any state that fails is fixed by adjusting the shape or drawing a regulated simplified version (8.01), not by letting the workshop whittle it down.
Place the candidate mark beside the marks of others in the same category, at the same size, in the same single colour, and glance to see whether it gets lost.
When it comes upBefore the final mark presentation, especially when the mark uses a shape common to the category (a leaf, a drop of water, a roof, an initial in a circle). A hypothetical example: a clean-vegetable business chooses a green leaf in a circle while half the stalls in the same market already use a green leaf.
A test to take home
(1) Collect the marks of businesses selling the same kind of product in the same places (taken from the category map of 2.03 if it exists). (2) Bring them all to the same small size and the same solid black, so only shape remains; colour is compared separately later. (3) Place the candidate among them, let a stranger look for a few seconds, then ask which is most different and which look alike. A candidate called similar to another mark fails, however unique it looks on the presentation board. (4) For a mark intended for trademark registration, also search registered figurative marks in the same class; figurative marks are classified by the Vienna Classification (the international classification grouping the figurative elements of marks, such as leaves, houses, circles, set up under the Vienna Agreement), so search by figurative group (leaf, house, circle), not only by name. Assessing likelihood of confusion in law is the job of an intellectual property specialist. Pass: the stranger points to the candidate as the most different.

A colour becomes an asset only when it is used the same way a great many times; one colour used consistently beats five colours used interchangeably.
When it comes upSettling the colour system, making campaign materials, launching a new product line, and when the in-house team wants to change colours for variety.
Resolution
The core colour is a constant, appearing in the same role on every touchpoint; secondary colours may change by campaign or line, provided they never take the core colour's place.
Full reasoning
Two goods pulling against each other
Many colours make materials lively, every campaign new, each product line its own colour, and the in-house team less bored. One core colour used consistently constrains the materials but builds recognition.
Why it holds
The eye catches colour from far away and from the corner of the eye, before it can read words or recognise shapes. But a colour carries no one's name by itself; it suggests a brand only once people have met that colour together with that brand often enough (0.4). Every time the brand appears in a different colour, the association is split. Five colours used interchangeably give five thin associations, and in a category where competitors also use those colours, none is thick enough to point to one business. The in-house team tires of a colour long before customers have had time to remember it, and that feeling is no reason to change (12.01).
When it fails
A brand architecture with several lines needs colour to help customers find the right product on the shelf (4.03, 4.07): then line colours do the finding, while the core colour must still hold a fixed place on every pack. In a category where a colour is an entry ticket (2.01), that colour distinguishes no one, and the asset must be found elsewhere.
What it costs
Campaign materials are constrained and designers have less room to play. Patience is needed through the period when the in-house team finds it dull but customers have not yet remembered it.

Set the proportion of colour use for each type of touchpoint, so the core colour takes the largest share of recognition rather than merely being present.
When it comes upWriting the colour section of the guidelines, and reviewing when the brand looks different everywhere even though everyone uses the correct colour codes.
A test to take home
(1) Photograph twenty touchpoints in use: posts, packaging, signs, uniforms, website, sales materials. (2) Arrange them in a grid and shrink or blur the image until text cannot be read. (3) Ask: which colour stands out? If it is a secondary colour, or every cell is a different colour, recognition is falling to the secondary colours even though the core colour is present somewhere. (4) Write proportion rules for each type of touchpoint, with visual examples and in words, stating what role the core colour plays (background, large areas, an identity bar) and how much room secondary colours may take. Pass: repeating the blur test at the quarterly review (11.05), the whole grid leans to one colour. Fail: the rules only list colour codes without saying which colour gets the most space.
A brand colour is a target with a tolerance range on each material and a master sample to arbitrate, not a code on a screen.
When it comes upSettling the colour system, handing colours to printers, sign makers, garment workshops, paint contractors and the web team; and when two touchpoints side by side do not match.
Resolution
No material can match another absolutely, so the designer's job is to define the target, the tolerance (the accepted deviation) for each material, and which material is the master when two disagree.
Full reasoning
Two goods pulling against each other
An absolute match makes the brand look polished, one colour everywhere. Accepting tolerance makes it workable on every material, faster and cheaper.
Why it holds
Screens emit light from three colours; paper, fabric, paint and plastic reflect the light falling on them. The same four-colour recipe (the four process inks cyan, magenta, yellow and black, usually called CMYK) printed on coated and uncoated paper already gives two colours, because the ink absorbs differently and the paper whites differ; the offset printing standard ISO 12647-2 therefore separates printing conditions by paper type. Dyed fabric, wall paint, acrylic, vinyl and lightboxes each have their own gamut, the set of colours that material can produce (the same red printed on glossy and matte paper already gives two reds), and many vivid screen colours exist on no material at all. Then the viewing light changes things further: two samples that match under one lamp may differ under another, so the print industry compares colour under standard light sources, specified in ISO 3664:2025 on viewing conditions. A colour code on a screen is therefore only a description, and without a master sample and a tolerance, each workshop will pick the nearest colour it can make: ten workshops, ten colours.
When it fails
A brand that lives only on screens has no materials to hand over, but customers' screens also vary from device to device, so it can still only be checked within a range. Colours carrying safety information or industry standards follow those standards, not the brand guidelines.
What it costs
Physical samples must be made, signed off and looked after; test prints cost money; and you must accept that with two materials placed side by side, a sharp eye will still see a small difference.

Define each brand colour by a signed physical sample together with a separate code for each material it will be used on.
When it comes upWhen writing the colour section of the guidelines, and before handing colours to a new workshop for the first time.
A test to take home
(1) Make a table: one row per colour, one column per material the brand actually uses (coated paper, uncoated paper, vinyl, fabric, paint, acrylic or lightbox, screen). Each cell holds the right kind of code for that material: a four-colour recipe for the printing condition, a spot colour code, a paint code, a screen colour code. An empty cell is where the workshop will guess. For lightboxes and illuminated signs, record the colour both unlit and lit, because the light's colour shifts the core colour. (2) For each main material, have the workshop make a colour sample on that exact material, compare under the same light source, sign and date the sample that passes; that sample, not a screen, is the master when there is a dispute. (3) Name one material as the master for the whole system, so that when two materials cannot both match, you know which must follow which. (4) Store samples in a dark folder with their date; paper and fabric samples also fade and yellow over time, so replace them when they differ from the signed state. Pass: a new workshop that has never worked with the brand produces colour within tolerance the first time, with only the table and the samples. Fail: screenshots have to be sent to explain the colour.
Choose outdoor colours and materials by their resistance to the sun, heat and humidity of the actual location, not by a test print viewed in an air-conditioned room.
When it comes upSigns, banners, window vinyl, awnings, delivery vehicles, packaging displayed at open stalls; in a hot, humid climate with harsh sun, a long rainy season and salt air near the sea.
A test to take home
(1) Ask the workshop three questions in writing: can this ink or paint be used outdoors, does it have a UV-resistant laminate or coating, and under what conditions does the material manufacturer state its outdoor durability. Many data sheets state durability by climate zone, and hot sunny zones are usually rated shorter; a figure stated for cold countries does not apply to a west-facing shopfront here. (2) Know which colours are weak: vivid colours such as red, pink, orange, lemon yellow and especially fluorescent colours usually fade faster than black, white and deep muted colours. If the core colour is in the weak group, plan a replacement schedule and budget, or choose materials coloured through their substance rather than printed on the surface. (3) Dark colours absorb heat: large dark panels in the sun warp easily and degrade adhesive, and vinyl peels sooner; ask the workshop about fixing and expansion gaps. (4) Hang a small sample facing the harshest sun at the actual location and keep an identical sample in the dark; after a few months compare them side by side; the trial sample comes from the same workshop and material as the production run, as in 10.05. For humidity and salt, also check panel edges, screw bases and lightbox seals. Pass: the chosen colour knows in advance how it will change and has a plan for it. Fail: the sign has faded before anyone learns the core colour is a weak colour.
